Abstract

An information recording apparatus with a capability of recording information to a plurality of non-contact recording media within a communicable range of the apparatus body, the apparatus including: a medium loading portion into which a non-contact recording medium is removably loaded; a medium detector configured to detect that a non-contact recording medium has been loaded in the medium loading portion; a first antenna for sending and receiving information to and from the non-contact recording medium loaded in the medium loading portion; a second antenna for sending and receiving information to and from the non-contact recording medium removed from the medium loading portion; and antenna switch for switching between the first antenna and the second antenna according to the detection output from the medium detector.

Claims

1. An information recording apparatus that records information to a plurality of non-contact recording media within a communicable range of a body of the information recording apparatus, the information recording apparatus comprising:

a medium loading portion into which a non-contact recording medium is removably loaded;

a medium detector configured to detect that the non-contact recording medium has been loaded in the medium loading portion;

a first antenna for sending and receiving information to and from the non-contact recording medium loaded in the medium loading portion;

a second antenna for sending and receiving information to and from the non-contact recording medium, when the non-contact recording medium is removed from the medium loading portion;

an antenna switch configured to switch a communication path between the first antenna and the second antenna according to a detection output from the medium detector; and

a communication unit configured to communicate with the non-contact recording medium using the first antenna or the second antenna via the antenna switch,

wherein, by communicating with the non-contact recording medium using the first antenna or the second antenna via the antenna switch, the non-contact recording medium loaded in the body is authenticated and provided with identification information via the first antenna, and when the non-contact recording media is removed from the body, at least one non-contact recording medium is selected from a plurality of non-contact recording media within a communicable range of the second antenna based on identification information provided via the second antenna to record, reproduce or delete information.

2. The information recording apparatus according to claim 1, wherein the medium loading portion is configured such that only one non-contact recording medium is removably loaded within a communicable range of the first antenna.

3. The information recording apparatus according to claim 1, wherein the communication unit selects multiple non-contact recording media from the plurality of non-contact recording media within the communicable range of the second antenna based on the identification information provided via the second antenna to simultaneously record, reproduce or delete information.

4. A non-contact recording medium to which information is recorded using an information recording apparatus that records information to a plurality of non-contact recording media within a communicable range of a body of the information recording apparatus, the non-contact recording medium comprising:

a loading detector configured to detect that the non-contact recording medium has been loaded in a medium loading portion of the information recording apparatus;

a first antenna that enables the non-contact recording medium loaded in the medium loading portion to send and receive information to and from the information recording apparatus;

a second antenna that enables the non-contact recording medium to send and receive information to and from the information recording apparatus, when the non-contact recording medium is removed from the medium loading portion;

an antenna switch configured to switch a communication path between the first antenna and the second antenna according to a detection output from the loading detector;

a communication unit configured to communicate with the information recording apparatus using the first antenna or the second antenna via the antenna switch;

an identification information storing unit configured to store identification information provided from the information recording apparatus, in an authentication process, during communication between the non-contact recording medium loaded in the medium loading portion and the information recording apparatus, via the first antenna, using the communication unit; and

an information storing unit configured to record, reproduce or delete information to, from or in the non-contact recording medium selected based on the identification information provided from the information recording apparatus, during communication between the non-contact recording medium that is removed from the medium loading portion and the information recording apparatus, via the second antenna, using the communication unit.

5. A recording method for a non-contact recording medium to which information is recorded using an information recording apparatus that records information to a plurality of non-contact recording media within a communicable range of a body of the information recording apparatus, the method comprising the steps of:

determining whether or not a non-contact recording medium is loaded in the information recording apparatus and switching a communication path between a first antenna switch for proximity-range communication and a second antenna for short-range communication according to the determination;

storing identification information, in an identification information storing unit in the non-contact recording medium loaded in the information recording apparatus, the identification information being provided from the information recording apparatus in an authentication process; and

performing recording, reproducing or deleting information to, from or in an information storing unit in the non-contact recording medium when the non-contact recording medium is removed from the information recording apparatus, the non-contact recording medium selected based on identification information provided from the information recording apparatus during communication between the non-contact recording medium and the information recording apparatus.
